Frequency Allocations
A.
Application
1)
This section addresses the 406.0-406.1 MHz transmitter window and the specific frequency band
allocations residing above 406.028 MHz, which are assigned or reserved within the 406.0-406.1 MHz
distress frequency window.
B.
Discussion
1)
The 406 MHz transmitter frequency of the C406-N Series ELT was originally 406.028 MHz. In order to
comply with COSPAS-SARSAT frequency allocation requirements, changes to the 406 MHz frequency
may occur since the original release of this product.
2)
While the original C406-N Series ELTs covered by this manual transmit on 406.028 MHz, current C406-N
Series ELTs may not. The product identification label on each ELT specifies the transmitting frequencies
of the individual ELT. The 406 MHz component may be 406.028, 406.037 MHz, etc. Allocation of
frequencies, based on beacon population per specified frequency band, is controlled by
COSPAS-SARSAT.
3)
The frequency references throughout this manual for the 406 MHz component should be considered the
baseline and the specific frequency indicated on the ELT product label should be substituted if it differs
from 406.028 MHz.
